+# Bridges
+
+High resolution image subset from the Aesthetic-Train-V2 dataset, contains a collection of bridges from various parts of the world including many iconic landmark bridges.
+
+## Dataset Details
+
+* **Curator:** Roscosmos
+* **Version:** 1.0.0
+* **Total Images:** 760
+* **Average Image Size (on disk):** ~5.7 MB compressed
+* **Primary Content:** Bridges
+* **Standardization:** All images are standardized to RGB mode and saved at 95% quality for consistency.
+
+## Dataset Creation & Provenance
+
+### 1. Original Master Dataset
+This dataset is a subset derived from:
+**`zhang0jhon/Aesthetic-Train-V2`**
+* **Link:** https://huggingface.co/datasets/zhang0jhon/Aesthetic-Train-V2
+* **Providence:** Large-scale, high-resolution image dataset, refer to its original dataset card for full details.
+* **Original License:** MIT
+
+### 2. Iterative Curation Methodology
+
+CLIP retrieval / manual curation.
+
+## Dataset Structure & Content
+
+This dataset offers the following configurations/subsets:
+* **Default (Full `train` data) configuration:** Contains the full, high-resolution image data and associated metadata. This is the recommended configuration for model training and full data analysis. The default split for this configuration is `train`.
+Each example (row) in the dataset contains the following fields:
+
+* `image`: The actual image data. In the default (full) configuration, this is full-resolution. In the preview configuration, this is a viewer-compatible version.
+* `unique_id`: A unique identifier assigned to each image.
+* `width`: The width of the image in pixels (from the full-resolution image).
+* `height`: The height of the image in pixels (from the full-resolution image).
+
+## Usage
+
+To download and load this dataset from the Hugging Face Hub:
+
+```python
+
+from datasets import load_dataset, Dataset, DatasetDict
+
+# Login using e.g. `huggingface-cli login` to access this dataset
+
+# To load the full, high-resolution dataset (recommended for training):
+# This will load the 'default' configuration's 'train' split.
+ds_main = load_dataset("ROSCOSMOS/Bridges", "default")
+
+print("Main Dataset (default config) loaded successfully!")
+print(ds_main)
+print(f"Type of loaded object: {type(ds_main)}")
+
+if isinstance(ds_main, Dataset):
+    print(f"Number of samples: {len(ds_main)}")
+    print(f"Features: {ds_main.features}")
+elif isinstance(ds_main, DatasetDict):
+    print(f"Available splits: {list(ds_main.keys())}")
+    for split_name, dataset_obj in ds_main.items():
+        print(f"  Split '{split_name}': {len(dataset_obj)} samples")
+        print(f"  Features of '{split_name}': {dataset_obj.features}")
+
+
